How to bundle JNLP API with Maven Project

I have a project where I need the JNLP API. I did not find an artifact for that on Maven Central, so I added an external Repository which offers that to my pom. That repository went offline this weekend. This is the second time something like this happened to me.

I know this is pretty much what Maven is not about, but really I just want that tiny jnlp-api-1.5.0.jar file to be

1. In my SCM (I don't want to roll my own Maven repository for just o开发者_运维问答ne dependency).
2. In the compile scope when the project builds.

Which knobs do I have to turn to accomplish this?

As of JDK 7.0, the JNLP API is being provided by the javaws.jar file in your JRE's lib directory, i.e., ${java.home}/lib/javaws.jar. It is possible to use the maven dependency scope system.

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>javax.jnlp</groupId>
      <artifactId>jnlp-api</artifactId>
      <version>7.0</version>
      <scope>system</scope>
      <systemPath>${java.home}/lib/javaws.jar</systemPath>
    </dependency>
  </dependencies>
  ...
</project>

You can put the JAR in your local repository using the install-file goal of the maven-install-plugin and reference it as you normally would in your POM. The command would be:

mvn install:install-file -Dfile=/path/to/jnlp-api-1.5.0.jar -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=1.5.0 -Dpackaging=<packaging>

Place this command in a script and check it into your SCM. That way, you (and anyone else working on this project) can install it easily to the local repo.
